1. Workshop U.S. Nuclear Regulatory Commission Rockville, Maryland Pacific Northwest National Laboratory November 15-17, 2005 3MRA

2. 2 The HWIR Question At what constituent concentration will wastes, when placed in non-hazardous waste management units over the unit’s life, result in: 1) greater than A% of the people living within B distance of the facility experiencing a risk/hazard of C or less and 2) greater than D% of the habitats within E distance of the facility with an ecological hazard less than F, at G% of facilities nationwide?

3. Land Application Unit 3MRA Question: Concentration in Effluent, prior to disposal?

13. 13 SUMMARYSUMMARY Protection of Human Health and Environment Practical and Cost-Effective Application of Risk-Based Decision-Making Consistent and Technically Defensible Tools to Support the Process Site-Specific or National Basis Framework Designed to meet intent of the HWIR Technology Software System:

14. 14 3MRA Storyboard Where to get 3MRA software EPA CEAM site How to enable 3MRA to run with FRAMES 2.0 Copy hwirio.dll from FRAMES 2.0 subdirectory to c:\3mra Copy import.0.hdssf to c:\3MRA\ssf for convenience How to import a 3MRA simulation into FRAMES 2.0 Use the 3MRA import tool What is produced by 3MRA models. Example output from Site Visualization processor

15. 15 Copy HWIRIO.dll to c:\3mra Copy 3mra\import.0.hdssf to c:\3mra\ssf for convenience

18. 18 The original SUI is presented but the underlying reading/writing is FRAMES 2.0

19. 19 Choose hdtest.ssf. If not available type in hdtest.ssf. Only hdtest.ssf will work for the filename.

20. 20 Use 0114001, Benzene, WP, CW=4 for speed sake. Any should work

21. 21 Make sure you are only running one realization for speed sake

22. 22 Pressing start will generate the case

23. 23 Bring up the FRAMES simulation editor

24. 24 Open the sim from the c:\3mra\ssf directory. Movement to FRAMESV2 is probably better.

25. 25 FRAMESV2 now has the CSM drawn for you. The Simulation is ready to Go.

26. 26 After waiting a little bit, the simulation comes back all green. File->Save to write the data to the files.

27. 27 FRAMES 2.0 result 3MRA Result

28. 28 A graphical form of the result from a viewer in FRAMES 3MRA not in 2.0 yet
